What is the best smart watch in the market today?

I want to buy a smart watch and there a couple of them available on the market. I would like some opinion from people who already owns a smart watch. My choices are between Pebble or Metawatch.

The smart watch is an emerging product in the market lately. Sony and Pebble are both popular choices when it comes to smart watches although Samsung and Apple are said to be making one as well. But between the choices that are available today, it is safe to pick Pebble.
